解析

试题分析：这篇短文主要讨论了去年冬天发生的雾霾天气。文中重点介绍了北京和西安的雾霾天气，并分析了造成此种天气的原因及对人们健康的危害。
小题1:联系上下文，可知此处指的是再出去以前。结合语境可知填介词before在……以前。
小题2:联系下文，可知他们希望以此能保护他们免受空气污染的伤害。结合语境可知填情态动词can，能，能够。
小题3:联系下文，可知在北京一月只有五天没有雾霾。结合语境可知填副词only，仅仅，只有。
小题4:联系下文，可知此处指的是看起来像雾和烟。结合语境可知本句描述的是客观性事实，故用一般现在时态。主语that表达抽象含义，故谓语动词用单数形式，填looks，看起来。
小题5:联系下文，可知此处指的是开汽车，动名词作主语表示抽象动作，联系下文可知填动名词driving，驾驶。
小题6:句意：不好的空间对人们的健康有害。结合语境可知填形容词bad，坏的，不好的，作表语。
小题7:联系下文，可知此处指的是温家宝做了他最后一次政府报告。结合语境可知本句描述的是过去发生的动作，故谓语动词用过去式，故填过去式动词made，使得，进行，制作。
